Mrs. Robert Dickson

On their way for subscriptions for the Avonlea hall to be reshingled and painted, Anne and Diana stayed for tea rather than risk offending Mrs. Dickson.

Clarice Almira Donnell

Clarice Almira is the daughter of Mrs. H.B. Donnell. On her first day of school in Avonlea with Anne as teacher, "she wore a faded pink silk dress, trimmed with a great deal of cotton lace, soiled white kid slippers, and silk stockings. Her sandy hair was tortured into innumerable kinky and unnatural curls, surmounted by a flamboyant bow of pinkribbon bigger than her head." She was the one who told her mother that Anne mispronounced their last name and called her brother Jacob instead of St. Clair.
AoA:Chapter 5

Mrs. H.B. Donnell

Mrs. Donnell is the mother of Clarice Almira and Jacob Donnell also known as St. Clair to his mother.

The newcomer [Mrs. Donnell] was gorgeously arrayed in a pale blue summer silk, puffed, frilled, and shirred wherever puff, frill, or shirring could possibly be placed. Her head was surmounted by a huge white chiffon hat, bedecked with three long but rather stringy ostrich feathers. A veil of pink chiffon, lavishly sprinkled with huge black dots, hung like a flounce from the hat brim to her shoulders and floated off in two airy streamers behind her. She wore all the jewelry that could be crowded on one small woman, and a very strong odor of perfume attended her.

She was "excessively annoyed" that Anne mispronounced her name as Donnell instead of Donnell. She was also unhappy that Anne referred to her son as Jacob instead of St. Clair.
